“…The citizens of Chios island are aware of the over-exploitation of groundwater that results in the salinization and the inflow of polluted waters into aquifers, making the water scarcity and the poor quality of their tap water one of the major problems of the island [57]. The way to address water scarcity and alter the water governance pattern requires trust, transparency and conceptual agreement between local government and residents [2,11]. In other words, if local governance would like to introduce the RWH as a sustainable system, it should also address social sustainability as a process and as a condition [58,59].…”

“…Rainwater Harvesting (RWH) has been identified as an alternative source of water supply for regions facing water scarcity [9][10][11]. However, until recently, it was not a widespread practice, and there was a debate about its efficiency, while installation costs were not fixed, and the knowledge about maintenance and probable risks was incomplete.…”

Rainwater Harvesting system (RWHs) can be considered as an alternative water resource in the era of the climate crisis. This research aims to study the effectiveness of a RWHs for domestic non-potable use and the water demand of the community in a Mediterranean site (Chios island, Greece). A water balance model is applied to simulate the behavior of a rainwater tank and calculate the daily water savings. The analysis correlates rainwater tank capacity, catchment area and population. The operation of the rainwater collection system has been calculated for seven years. In order to assess the investment risk regarding the application of the RWHs, the financial ratio of PayBack (PB) period was determined. The multifaceted character of Rainwater Harvesting (RWH) practice in the three-dimensional concept of sustainability is discussed. This study concludes that RWH contributes to the greening of society, dealing with water scarcity in urban areas.

“…Tot dusverre hebben bijdragen aan een discussie over deze onderwerpen zich toegespitst op technologie-gebaseerde platformen als een economisch verschijnsel (zoals de 'sharing economy; Frenken, 2016), of op sectorspecifieke ontwikkelingen zoals de rol van energie-coöperatieven in de energie transitie (bijv. Yildiz, 2014), gezondheids-en veiligheidsaspecten van off-grid watervoorzieningen (Sojka et al, 2016), en de waarde van (digitale) informatie in bevoorradingsketens (bijv.

De crowd speelt steeds vaker een sleutelrol in innovaties. Dergelijke 'crowd-based innovaties' bieden veel kansen voor vernieuwing in socio-technische systemen, bijvoorbeeld doordat meer mensen, makkelijker mee kunnen doen. Tegelijkertijd brengen zij belangrijke uitdagingen met zich mee doordat deze nieuwe praktijken plaatsvinden in een gevestigde institutionele en governance context. Deze dynamiek is te vangen in het idee van een 'institutional void': de spanning tussen (radicaal) nieuwe initiatieven en de geijkte structuren, regels en routines. Dit roept vragen op over het waarborgen van (publieke) waarden bij crowd-based innovaties. In dit artikel betogen we dat dit fenomeen vraagt om meer, gedegen empirisch onderzoek maar dat ook normatieve kwesties moeten worden meegenomen. Aan de hand van een typologie en drie voorbeelden wordt deze dynamiek beschreven en komen we tot een multidisciplinaire onderzoeksagenda voor andere governance structuren, waarbij innovaties niet voor de voet gelopen worden maar er wel aandacht blijft voor de waarde van bestaande instituties. English summary: Crowd-based innovations: shifting responsibilities in an institutional voidThe crowd increasingly plays a key role in facilitating innovations in a variety of sectors, spurred on by IT-developments and the concomitant increase in connectivity. Initiatives in this direction, captured under the umbrella-term 'crowd-based innovations', offer novel opportunities in socio-technical systems by increasing the access, reach and speed of services. At the same time, they signify important challenges because these innovations occur in a context of traditional, well-established institutional and governance structures and practices. This dynamic is captured in the idea of the 'institutional void': the tension between traditional structures and (radically) new initiatives. Existing rules, standards and practices are challenged, which raises questions about the safeguarding of public values such as quality, legitimacy, efficiency and governance of crowd-based innovations. This article argues that understanding these tensions requires supplementing empirical research with an explicitly normative dimension to reach thorough and balanced conclusions to facilitate innovation while protecting the valuable elements in existing rules and regulations. Illustrated by a number of short examples, we propose a multidisciplinary research agenda towards formulating appropriate governance structures.

“…In the U.S., interest in RWH is growing due to increased droughts as well as its environmental benefits ( Thomas et al, 2014 ; Sojka et al, 2016 ). An energy and greenhouse gas (GHG) emission analysis of RWH in a university building in Ohio reported RWH as a viable option with GHG emission payback periods higher than the energy payback periods but contradicted the results of Anand and Apul (2011) due to difference in data sources (process-based versus Economic Input Output life cycle assessment data) ( Devkota et al, 2015 ).…”

Building upon previously published life cycle assessment (LCA) methodologies, we conducted an LCA of a commercial rainwater harvesting (RWH) system and compared it to a municipal water supply (MWS) system adapted to Washington, D.C. Eleven life cycle impact assessment (LCIA) indicators were assessed, with a functional unit of 1 m3 of rainwater and municipal water delivery system for toilets and urinals in a four-story commercial building with 1000 employees. Our assessment shows that the benchmark commercial RWH system outperforms the MWS system in all categories except Ozone Depletion. Sensitivity and performance analyses revealed pump and pumping energy to be key components for most categories, which further guides LCIA tradeoff analysis with respect to energy intensities. Tradeoff analysis revealed that commercial RWH performed better than MWS in Ozone Depletion if RWH’s energy intensity was less than that of MWS by at least 0.86 kWh/m3 (249% of the benchmark MWS energy usage at 0.35 kWh/m3). RWH also outperformed MWS in Metal Depletion and Freshwater Withdrawal, regardless of energy intensities, up to 5.51 kWh/m3. An auxiliary commercial RWH system with 50% MWS reduced Ozone Depletion by 19% but showed an increase in all other impacts, which were still lower than benchmark MWS system impacts. Current models are transferrable to commercial RWH installations at other locations.
